What is the general maximum working pressure of air pressure pipelines?

The maximum working pressure of the air pressure pipeline shall be comprehensively determined according to the pipeline material, design standards and actual use scenarios, and the core is to ensure the safety of gas supply and equipment stability.

1. The pressure range
of common industrial scenes The design maximum working pressure of general industrial air pressure pipelines is usually between 1.0-1.6 MPa (about 10-16kg force per square centimeter), which can cover the needs of most manufacturing and processing scenes. For example, automated production lines, pneumatic tool drives and other links, this pressure range can not only meet the power needs, but also meet safety specifications.

2. The influence
of pipe material The pipe material directly determines its pressure bearing capacity. Steel pipes are often used in high-pressure scenes (e.g. above 1.6 MPa) due to their high strength. Aluminum pipes or plastic pipes (such as PA and PE) are mostly used in low-pressure scenes (such as below 1.0 MPa). The suitable material shall be selected according to the actual working pressure to avoid pipeline deformation or rupture caused by insufficient pressure of the material.

3. Safety design and standards are based
on national or industrial safety standards (such as GB/T 20801 "Pressure Pipeline Code") for the design of air pressure pipelines. Generally, the nominal pressure (design pressure bearing capacity) of pipelines is required to be 20%-30% higher than the actual working pressure, and a safety margin is reserved. For example, if the output pressure of the air compressor is 1.0 MPa, the pipeline design should be selected according to the pressure bearing capacity of at least 1.2-1.3 MPa to cope with the pressure rise caused by pressure fluctuation or temperature change.

4. Environmental considerations
changes in temperature will affect the pressure of compressed air in the pipeline (such as high temperature leads to gas expansion, low temperature may cause pipeline condensate ice expansion). The design needs to adjust the pressure standard of the pipeline according to the ambient temperature range, for example, in the high temperature workshop or outdoor scene, the pipeline needs to have a higher safety margin.

To sum up, the maximum working pressure of the air pressure pipeline should be determined comprehensively according to the material, scene and safety standards, and the core is to ensure the stability and safety of the gas supply process. Granklin air compressor output compressed air pressure is adjustable, adapt to different pipeline design requirements, while its oil-free characteristics reduce the risk of oil accumulation in the pipeline, further ensuring the reliability of pipeline operation.
